Abstract

Backup schedule optimization is provided. Backup environment data is identified. Data describing a first backup schedule is identified. Performance metric data that includes data for a data storage array of computer data storage device(s) of a backup server is collected. Data describing backup log(s) that associated with jobs backed up to the data storage array and respectively executed during backup window(s) is received. A target average I/O rate is determined based on the performance metric data of the data storage array. A second backup schedule is generated based on the target average I/O rate, average I/O rate(s) of the data storage array, the backup environment data, and the data describing one or more backup logs. A start time of a job is scheduled in the second backup schedule for a different time in a backup window compared to a start time of the job in the first backup schedule.

Claims20

Dependent claims

A method for optimizing data backup schedules, comprising:

identifying, by one or more computer processors, backup environment data;
identifying, by one or more computer processors, data describing a first backup schedule;
collecting, by one or more computer processors, performance metric data that includes performance metric data of a data storage array of one or more computer data storage devices of a first backup server;
identifying, by one or more computer processors, data describing one or more backup logs that are associated with a plurality of jobs that were backed up to the data storage array and respectively executed during one or more backup windows;
determining, by one or more computer processors, a target average I/O rate based, at least in part, on the performance metric data of the data storage array;
and
generating, by one or more computer processors, a second backup schedule based, at least in part, on the target average I/O rate, one or more average I/O rates of the data storage array, the backup environment data, and the data describing the one or more backup logs such that a start time of a first job of the plurality of jobs in the second backup schedule is scheduled for a different time in a backup window compared to a start time of the first job in the first backup schedule.
